Index Ventures
Holmes has been working at Index Ventures since 2002, and led investments in companies including "Candy Crush" developer King, iZettle, Just Eat, Notonthehighstreet, and Trustpilot.
Index Ventures said Holmes has moved from a general partner role seeking new deals to a venture partner job where he works with existing investments.
"He isn't leading new deals on behalf of Index," the VC firm said in an email to Business Insider. "He made the decision to transition gradually out of Index to explore other opportunities after 14 successful years with the firm. Ben remains a close member of the Index family."
An email sent by Holmes about his change of role said: "My energies will be focussed on managing the existing investments for which I am responsible. In addition I will continue to funnel relevant new opportunities to colleagues at Index, but won't be personally leading new investments on behalf of the firm."
Companies House records show that Holmes was removed as a member of the Index Ventures limited liability partnership on December 31. Around the same time, Holmes changed his Twitter username from @indexben to @bendotvc.
